New evidence of Japanese germ warfare unit made public

Six pages in length, and classified as a military secret, the rosters were compiled by the Japanese Kwantung Army in August 1940, and discovered in the National Archives of Japan as a result of the cooperation of the exhibition hall and Japanese scholar Seiya Matsuno.

Furthermore, clues about cooperation between a Japanese army hospital in Harbin and Unit 731 in a plague outbreak in Jilin Province have also been discovered.

A document showed that in October 1940, the Japanese Kwantung Army dispatched the Japanese army hospital in Harbin to engage in the "prevention and control" of plague bacteria carried out by Unit 731, which was, in fact, operations to test the results of a plague bacteria attack in the name of outbreak control.
